HM1-7603-5

HM1-7603-5: 256-Bit (32 Words x 8-Bit) Monolithic Schottky TTL Bipolar Field-Programmable ROM (PROM), featuring a fast 50-nanosecond maximum address access time profile. The "3" matrix designator specifies 3-State (Tri-State) non-inverting outputs governed by a dedicated active-low chip enable (\(\overline{\text{CE}}\)) terminal. It utilizes high-durability internal nichrome fuse links to enforce absolute non-volatile data retention, storing permanent microprogram control words and high-speed address lookup algorithms with zero performance drift, housed in a standard 16-pin hermetically sealed ceramic dual in-line package (CerDIP) layout.
